Roll Anode 120 Zinc Sacrificial
Zinc sacrificial anodes for corrosion control of steel in concrete according to EN 12696
RollAnode 120 is specifically designed for application in pre-drilled holes which are imbedded in an ion-conductive auto moistening paste, for cathodic protection of reinforced concrete structures. Chlorides free acc. to EN 1504 specifications.
Product description
The Rollanode 120 consists of rolled up layers of zinc with ion-conductive gel which after applied in concrete will be covered with an ion-conductive self-moistening overlay paste keeping the anodes active during their entire service-life. This paste (ZAP = Zinc anode Activation Paste) is delivered seperately in 600ml sausages which can be applied with standard manual or battery powered sealant guns. These anodes are utilized in those areas where high expectancy of corrosion is expected. They guarantee a strong reduction of corrosion and preventing new locations with initiation of corrosion.
The service life of the anodes is directly related to the following variables : total zinc weight per unity surface area, steel surface area (steel density), presence and availability of oxidizing agents (O2, H2O) to maintain the cathodic reactions on the steel structure, and the anode’s capacity.
Thanks to the simplicity and quickness of the installation, application costs can be reduced to a minimum. The eventual driving force between those anodes and the steel reinforcement guarantees a long and corrosion-free service life of the structure.
